1 Claim. or. 30-53 The present invention relates to shaving equipmentand in particular to a complete razor, including both blade and supporttherefor, that can be provided at such low cost as to be disposableafter but a single'use thereof.

A major object of the invention is to provide an efiicient razor that isintended for temporary use, as when traveling or'when temporarily andunexpectedly detained in a hospital or other institution.

Another object of the invention is to supply a disposable razor that canbe included in a shaving kit for coin-machine vending or distributedfree of charge by 2,817,897 Patented Dec. 31, 1957 could be used forthis purpose if desired. Frame member F is an elongate, substantiallyrectangular sheet of such material consisting of a handle portion and ablade-holding portion 12 that is a linear extension of said handleportion. Handle portion 10 is, of course, sufficiently long to beconveniently grasped in the fingers for manipulation and may be providedwith a rounded first end 14. The opposite sides 16 of frame member F arepreferably flat and the second end 18 of said frameis 0 straight.

hospitals,.jails or other institutions, the razor being constructed insuch an economical manner thatit can be sold ata .low price,ordistributed at a very nominalpriee, or free, its cost being verynearly inconsequential.

A still further object of the invention is to furnish a disposable razorthat is made very easily from a minimum number of parts and having asimple yet effective manner of securing the blade to the handle.

These and other objects and advantages of the invention will becomeapparent from the following description of a preferred form and certainvariations thereof, and from the drawing illustrating those forms inwhich:

Figure 1 is a perspective view of said preferred form of my invention;

Figure 2 is an exploded perspective of the device shown in Figure 1,with parts thereof cut away to show details of its interiorconstruction;

Figure 3 is a vertical cross-sectional view taken along the line 33 ofFigure 1;

Figure 4 is a vertical cross-sectional view of one variation of mydisposable razor invention;

Figure 5 is a partial perspective view of a second variation of myinvention;

Fgure 6 is a vertical cross-sectional view of the device shown in Figure5 taken on the line 6-6 of Figure 5;

Figure 7 is a perspective view of still another variation of myinvention; and

Figure 8 is a vertical cross-sectional view taken along the line 8-8 ofFigure 7.

Referring now to the drawing for the general arrangement of theinvention and in particular to Figures 1 and 2, it will be seen that anelongate rigid frame member F and blade B constitute the razor R of thepresently preferred form of my invention. It will be noted that therazor R is not of the safety-type, but rather resembles the straightrazor, and its extremely low cost is, in part, attributable to thisconstruction. As will become apparent, even though razor R resembles theconventional straight razor, it nevertheless avoids the relativelyhigher cost of a rigid hollow-ground blade, although that type of bladecould be used, by providing means of supporting a wafer-thin blade withsufiicient rigidity to enable it to readily cut the users beard.

In order to keep the cost of razor R very low, it is preferred thatframe member F be made of wood, although a strip of metal or plastic orother rigid material Blade-holding portion 12 is best seen in Figure 2.An open-ended slot 20 is formed along the longitudinally extendingcenterline of portion 12, extending from straight end 18 thereof towardhandle portion 10. Although not absolutely necessary, I prefer that slot20 taper inwardly slightly, its width decreasing as it pro gressestoward handle portion 10. Blade-holding portion 12 being thus bifurcatedby slot 20 is divided into two branches 22 between which a portion ofthe structure of blade member B can be inserted.

Blade member B includes two blade arms 24 that are transversely spacedapart the same distance as the thickness of blade-holding portion 12 andto which arms a web 28 is affixed, as by welding, to the inwardly facingsurfaces thereof along the longitudinal centerlines of arms 24. As canbe seen in Figure 3, web 28 is substantially rectangular incross-section and may, if desired, be formed with a taper to conform tothe taper of slot 20 of blade-holding portion 12. Web 28 is ofsubstantially the same length as slot 20 and is frictionally receivedtherein, branches 22 of portion 12 being resiliently deformable to holdsaid web with a tight fit. When relatively thin blade material is used,it will be found advisable to further secure blade B to frame F by meansof pins 30 fastened transversely through blade member B and branches 22of blade-holding portion 12. The inwardly facing surfaces of blademember B are then securely held in abutting relationship to flat sides16 of frame member F to be rigidly supported thereagainst so that whenone of cutting edges 26 is used in shaving, in the manner of Figure 3,there will be no deflection thereof. The manner of use of razor R isentirely conventional, as Figure 3 shows.

Figure 4 depicts a variation of my invention in which a frame F supportsa single blade B in such a way that one edge portion of said frame actsas a steady rest or guide. Frame F is also an elongate rectangular fiatmember like frame member F, but its upper and lower edges 32 aresmoothly rounded. To one of its flat sides 16' along the longitudinalcenterline thereof, frame F at one end has double-edged blade B rigidlyaflixed thereto. Said blade is made of a rectangular strip of metalmaterial sufliciently thick to be internally rigid and is provided withtwo hollow-ground cutting edges 34 but is not as wide as frame F. BladeB lies in a plane parallel to and transversely spaced apart from frameF, as by means of spacer 36, which can also be the fastening means.

It can be seen by reference to Figure 4 that the manner of use of razorR is slightly different from the manner of using razor R. Frame F isheld in such a manner that one of its edges 32 rests on the skin of theuser with a cutting edge 34 disposed in shaving engagement with thebeard but steadied by frame edge 32.

Another variation of my invention similar in use to razor R is shown inFigure 5, indicated generally by the letter I. Razor I can be stampedfrom a single elongate sheet 38 of metal to provide a singularlyeflicient, lowcost disposable razor. Although not shown in Figure 5, itwill be understood that sheet 38 at one end includes a handle portion.At its other end a longitudinally extending centrally disposed bladestrip portion 40 of sheet 38 is'depressed outwardly beyond the plane ofone of its sides. Either before or after the forming of blade strip 40,sheet 38 is formed into the cross-sectional arcuate configuration shownin Figure 6, having convex side 42 and concave side 44 so that bladestrip 40 protrudes outwardly from said convex side. The longitudinaledges of blade strip 40 are then ground to form cutting edges 46. AsFigure 6 indicates, the manner of use of razor I is the same as the useof razor R, but as razor I advances over the beard, the removed beardand shaving cream pass behind blade strip 40 into the void space ofsheet 38 left by formation of said strip. With this construction it isnot necessary to wash accumulated lather and removed beard from theinvention with as great a frequency as may be required with razor R.

Razor 0 of Figures 7 and 8 presents yet another variation of myinvention. Handle 48 of razor O is simply an elongate rectangular, fiatsheet, preferably of wood, and suggestive in appearance of frame memberF of my preferred form of invention. However, razor O is provided with adifferent form of blade 50 attached to handle 48 in a different way.Blade 50 is intended to ,be formed of sheet metal that is capable ofbeing folded along its longitudinal centerline to define a transverselyU- shaped configuration having two equal legs 52. Said legs are spacedapart the same distance as the thickness of handle 48, with one endportion of handle 48 being inserted therebetween. As can best be seen inFigure 8, the longitudinal edge portions 56 of blade 50 are flaredoutwardly away from one another and from sides 58 of handle 48 and arehardened and ground to define cutting edges, 60. A pair of pins 30extending transversely 4 through handle 48 and blade 50 securely fastenthem to one another. It will be apparent that if desired, the pins 30may be eliminated by so spacing legs 52 that they frictionally engagehandle 48.

Although the forms of the invention herein shown and described are fullycapable of achieving the objects and providing the advantageshereinbefore mentioned, it is to be understood that they are merelyillustrative of presently preferred embodiments thereof and that I donot mean to limit myself to the details of construction herein shown anddescribed other than as defined in the appended claim.

I claim:

A razor that comprises a frame member that is made of a rigid materialand including an elongated handle portion and a blade-holding portionbeing an extension from said handle portion; and a blade member rigidlyaflixed to said blade-holding portion that comprises an elongaterectangular sheet of a'rnetal that is folded along the longitudinalcenterline thereof into a U-shaped cross-section to define a pair oftransversely spaced apart legs that are adapted to frictionally receivetherebetween said bladeholding portion, with the longitudinallyextending edges of said blade member sharpened and flared outwardly awayfrom said frame member.
